OPTIMIZE YOUR NATURAL CYCLES & BIORHYTHMS TO RISE, sleep, THINK, AND EAT AT IDEAL TIMES

Do you ever feel out of sync with your natural cycles? Circadian is the leading circadian rhythm app designed to help you realign with your body's natural clock. By tuning into your circadian rhythm and honoring your biorhythms, you can enjoy better sleep, balanced hormones, and a healthier lifestyle overall. Discover the power of living in harmony with nature's timing.

☀️ ALIGN WITH SUNLIGHT & SEASONS
Why dissect every sleep cycle or follow a rigid sleep calendar when natural cycles offer the best guidance? This circadian rhythm app harnesses diurnal patterns—including sunrise, UVA/UVB light rise & set, solar noon, sunset, and darkness—to provide consistent rise & sleep reminders and wind-down alerts. Trust your internal clock to help you establish a smooth sleep rhythm and a natural circadian sleep pattern. Embrace a life synchronized with the sun and seasons.

? BEDTIME CALCULATOR & BIORHYTHM CALCULATOR
Plan your optimal hours of sleep and fasting windows with our seasonal bedtime calculator and robust biorhythm calculator. Swap rigid schedules for nature’s timing: anchor bedtime to dusk and wake with the sunrise. Our bedtime calculator uses your rise time and the optimal seasonal sleep duration to calculate your ideal bedtime. Studies confirm that syncing with natural cycles outperforms any generic sleep cycle tracker. Let natural cycles guide you to entrain your biorhythm with optimal reminders for better sleep, meals, work, and exercise times.

? EAT & FAST IN SYNC WITH NATURE
Intermittent fasting and time-restricted eating are most effective when aligned with daylight. Front-load your calories at sunrise and close your eating window by dusk to match your circadian rhythm. Research shows that skipping breakfast or dining late disrupts this rhythm and harms metabolic health. With Circadian, set eating & fasting reminders that honor this timing for balanced blood sugar and deeper sleep. Optimize your metabolic health by eating in harmony with nature.

? THE SCIENCE OF CIRCADIAN RHYTHMS
Built on Nobel Prize–winning chronobiology, this circadian app explains how your internal clock and biorhythms regulate melatonin, cortisol, and vitamin D production. Getting the right circadian cues—light/darkness, Food & exercise—at the right time is essential for a healthy body, mind, and heart. Use Circadian and its extensive learn & research section for tons of actionable insights on your sleep rhythm, artificial light, exercise timing, diurnal living, and much more to transform your natural life. Understand the science behind your body's natural rhythms.

⏰ YOUR NATURAL ALARM CLOCK
Wake gently with circadian rhythm alarm clock features: rise with the sun to greet the day. Getting natural light into your eyes for just 5 minutes upon waking improves your sleep quality the next night by 20%!
